Plane is visible despite blend mode set to alpha blend
So I found the issue had to do with Volumetric lighting in the render properties. I had changed the light clamping to 0.050 and now the planes are no longer visible like the picture. The annoying thing is changes in the light or volumetric scatter setup has me needing to adjust the clamp to lower numbers. I decided to use cycles instead, longer render times but this issue is no longer present.
